Question 1:
DTV and Dish do not (yet) offer locals in HD. You will need an external antenna (rabbit ears or outside) to receive locals in HD.
Question 2:
I'm a DTV subscriber; can't answer Dish 811 question
Question 3:
Your distance from the OTA stations is quite substantial. However a large outside antenna w/amp could do the trick. Just be sure to add an antenna rotator if the stations come from different locations (posted on the CEA website).
